"XCPUScalar"
for Pocket PC has been nominated for a 2007 Best Software Award in the category "Utilities,
Overclocking / Speed Boosting" by the Smartphone & Pocket PC magazine
staff and its Board of Experts!

XCPUScalar allows you to dynamically scale the processor speed of your
handheld Pocket PC 2002, Windows Mobile 2003, WM2003 SE, and Windows Mobile 5. It uses the power of the XSCALE
or TI OMAP (OMAP850 and OMAP1510)
processor and unlocks its dynamic scaling capabilities. You can scale the
processor speed from 100 to 728MHz. By scaling the processor speed down, you can increase the battery life between recharges or increase the speed when you need more power for playing
games or multimedia programs that require more CPU power.

The speed can be scaled from 100 to 300MHZ on the fly for the iPaq 1910 ,100 to 500MHz for
PXA250 XSCALE processors and 100 to 530MHz at 265MHz bus for PXA255, PXA26x, and
104 to 728MHz for PXA270, PXA27x or
higher processors. For TI OMAP processors the speed can be scaled from 104MHz to
260MHz. Use the Auto Scaling
capability of XCPUScalar and assign your own speeds to different CPU loads as
shown in the picture above. With Auto Scaling, applications will get power on
demand depending on CPU usage, saving battery life. Monitor CPU usage as you run
your applications, XCPUScalar integrates with popular task managers like Wisbar,
Icbar, and Gigabar. Monitor the health of your Pocket PC using the health
meters. iPAQ 1910 users can almost double their framerates when watching movies
or playing games.

PDA's based on XSCALE processors can enjoy speed increases of upto 30
to
35% (QUAKE timedemo1 test scores , reported 33 FPS using XCPUScalar on an Axim
X30, on iPAQ 2215 is around 20 to 21 FPS. Speed will slightly vary from PDA to PDA. ).

Compatibility:

XCPUScalar should work with most XSCALE or TI OMAP
Pocket PC's on market. Minimum Windows mobile 2003 and XScale or TI OMAP
processor PDA required. Some of the known supported PDA's include:

We use safe and overclocked frequencies that have been thoroughly tested out and stable. If you
want to remain on the conservative side, use only the safe frequencies. The
About tab of the utility will tell you the safe industry standard frequencies to
use. For more info, read the What's New section.
